Welsh nuke shut down following steam leak

Wales Online reported today:

An ageing nuclear reactor has had to be shut down due to a “steam leak” only days after it was re-started.

Reactor one at Wylfa nuclear power station, on Anglesey, in North Wales, was shut down on Thursday, say owners the Nuclear Decommissioning Authority (NDA).

The NDA say the reactor had been re-started two days earlier on July 1 in a “slow, controlled manner just in case there were any issues”.

The Wylfa station originally consisted of two Magnox reactors which came online in 1971. The two reactors were originally intended to produce 1190 megawatts of power, but problems with the graphite core, corrosion of steel elements and higher than expected channel gas outlet temperature prevented operation at the expected output. With the technical issues and following the retirement of Unit 2 in 2012, output for the remaining reactor is limited to 490 megawatts.

The sole remaining reactor had been shut down for maintenance:

Reactor one was first shut down by operators Magnox on January 6 for maintenance work and its re-start was twice delayed when problems were discovered.
